I have installed Wilwood front calipers on my project car. Drums will be used on the rear. what size brake hoses should I use on the front calipers? I already have some AN#4 hoses and would like to use them if they will work OK. The master cylinder is a stock one for a 73 disc brake A-body. Thanks you in advance for your experience/replies. Jim

I used these

WildBill thanks for that link. I see those are #3 lines. I'm just wondering if the #4 lines that I already have would be too big? Jim

I thought fluid pressure would stay the same, ina slightly larger line, and just push extra volume by the MC.

3/16 - #3 an works fine

#4 will work for brakes as long as the lines are capable of handling the pressure. #3 is usually used for brake lines since it is stronger.
